The Chesapeake Bay, an area of approximately 200 miles, is North America's largest estuary. The Bay and its tributaries comprises a complex ecosystem which encompasses rivers, wetlands, trees and habitats. This animation takes us on a tour around the Bay starting from its 'mouth' near Norfolk, Virginia, flying north up to the Susquehanna River and then flying down the area of the Eastern Shore all the way to the Fishermans Island, zooming out to get a look of the Chesapeake bay region. The imagery utilized for this animation is a false-color Chesapeake Bay Landsat-7 Mosaic (#3473) composed of eight scenes acquired between 1999-2002, which were put together and color corrected to resemble natural looking colors.
The mosaic was created by EarthSat under contract with NASA as part of the GeoCover 2000 product. All images used in GeoCover were acquired by Landsat 7 during the period of 1999-2002. The pixel size of the full resolution image represents 14.25 m on the ground. The Chesapeake Bay mosaic uses portions of eight Landsat-7 scenes. Below you will find a listing of the eight Landsat 7 images that were put together to create the composite image. Landsat scenes are organized by a Path and Row number according to the Worldwide Reference System.
